[0031] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings. In addition, the terms "first", "second" and "third" in the embodiments of the present application are only used to distinguish and have no substantial meaning.
[0032] Figure 1 is a schematic diagram of the structure of a display panel provided in an embodiment of the present application, Figure 2 yes Figure 1 Schematic diagram of the structure of a pixel repeating unit in the display panel shown in FIG. Figure 1 and Figure 2 The display panel 100 includes a plurality of pixel repeating units arranged in an array, and the pixel repeating units include two first sub-pixels 11, two second sub-pixels 12 and four third sub-pixels 13; in the display panel: there is a first sub-pixel 11 located between four third sub-pixels 13; there is a second sub-pixel 12 located between four third sub-pixels 13; there is a third sub-pixel 13 located between two first sub-pixels 11 and two second sub-pixels 12 at the same time; the centers of the four third sub-pixels 13 surrounding the first sub-pixel 11 form a first irregular trapezoid 21, wherein the lengths of two sets of opposite sides of the first irregular trapezoid 21 are not equal.
[0033] like Figure 2As shown, in the pixel repeating unit, a first sub-pixel 11 (such as the first sub-pixel 11 at the upper left corner) is located between four third sub-pixels 13, and there is a third sub-pixel 13 (such as the third sub-pixel 13 at the lower right corner) that is simultaneously located between two first sub-pixels 11 and two second sub-pixels 12. In this way, by arranging the pixel repeating unit along Figure 1 The array is arranged in the first direction and the second direction, which can form Figure 1 The display panel is shown.
[0034] Specifically, Figure 1 As shown, in the display panel, the first sub-pixel 11 is located between four third sub-pixels 13, the second sub-pixel 12 is located between four third sub-pixels 13, and the third sub-pixel 13 at the non-edge is located between two first sub-pixels 11 and two second sub-pixels 12. Figure 1 It can be seen that compared with the existing RGBG or YYG arrangement, the pixel arrangement in the display panel provided in the embodiment of the present application can make the distribution of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 in the display panel more uniform, thereby improving the display effect of the display panel.
[0035] The first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 emit different colors. Optionally, the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are respectively one of a red sub-pixel, a blue sub-pixel and a green sub-pixel and are different from each other.
[0036] For example, the first sub-pixel 11 may be a blue sub-pixel, the second sub-pixel 12 may be a red sub-pixel, and the third sub-pixel 13 may be a green sub-pixel, or the first sub-pixel 11 may be a red sub-pixel, the second sub-pixel 12 may be a blue sub-pixel, and the third sub-pixel 13 may be a green sub-pixel. In this way, each pixel setting area 10 may include a blue sub-pixel (or a red sub-pixel) and a green sub-pixel, and thus color display may be achieved through a pixel rendering method, and image resolution (PPI, Pixels Per Inch, the number of pixels per inch) may be improved.
[0037] Among them, the pixel setting area 10 is Figure 1 and Figure 2 A rectangular area defined by a plurality of dotted lines extending along the first direction and the second direction. Figure 1As shown, the pixel setting area 10 covers the entire area of a first sub-pixel 11 and partial areas of four third sub-pixels 13 surrounding the first sub-pixel 11 (the sum of the areas of the partial areas of the four third sub-pixels 13 is equal to the area of one third sub-pixel 13), or covers the entire area of a second sub-pixel 12 and partial areas of four third sub-pixels 13 surrounding the second sub-pixel 12 (the sum of the areas of the partial areas of the four third sub-pixels 13 is equal to the area of one third sub-pixel 13). Therefore, a pixel setting area 10 includes a first sub-pixel 11 (such as a blue sub-pixel) and a third sub-pixel 13 (such as a green sub-pixel), or a pixel setting area 10 includes a second sub-pixel 12 (such as a red pixel) and a third sub-pixel 13 (such as a green sub-pixel).
[0038] It should be noted that Figure 1 and Figure 2 In the figure, only the shapes of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are all rectangular for illustration, and the embodiment of the present application does not specifically limit the shapes of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13. The boundary of the rectangle represents the opening boundary of the corresponding sub-pixel. Taking the display panel as an OLED display panel as an example, the boundary of the rectangle is the boundary of the effective opening of the sub-pixel of the pixel definition layer (PDL layer), which represents the light-emitting area (opening area) of the sub-pixel.
[0039] It should also be noted that Figure 2 The pixel repeating unit shown is only an example and not a limitation. For example, four third sub-pixels 13 in the pixel repeating unit may be arranged around the same second sub-pixel 12 , and one of the third sub-pixels 13 may be located between two first sub-pixels 11 and two second sub-pixels 12 at the same time.
[0040] Further, from Figure 1 It can be seen that the embodiment of the present application can make full use of the design space of the display area and make the pixel arrangement more compact by setting the centers of the four third sub-pixels 13 surrounding the first sub-pixel 11 to form a first irregular trapezoid 21 with two sets of unequal opposite sides. Among them, the center of the (third) sub-pixel refers to the geometric center of the light-emitting area of the sub-pixel, which can be determined according to the shape of the sub-pixel. Here, the shape of the sub-pixel is a rectangle as an example for illustration.
[0041] In addition, compared to the scheme in which the centers of the four third sub-pixels (such as the green sub-pixel) surrounding the first sub-pixel (such as the red sub-pixel or the blue sub-pixel) form a rectangle (such as the diamond arrangement), in the present embodiment, since the centers of the four third sub-pixels 13 surrounding the first sub-pixel 11 form an irregular trapezoid, when the area of the display area is constant, the same number of third sub-pixels 13 can be set in the display area by reducing the light-emitting areas of some or all of the third sub-pixels 13 to ensure that the pixel resolution PPI remains unchanged. When the light-emitting area of the third sub-pixel 13 is reduced, on the one hand, the opening area of the corresponding mask can be reduced, thereby enhancing the strength of the mask and improving the yield of the evaporation process; on the other hand, for the OLED display panel, the sub-pixel includes a light-emitting element. It is easy to understand that when the light-emitting layer area of the light-emitting element (OLED) is reduced, the area of its anode can be reduced. In this way, for technologies such as under-screen fingerprint recognition (FOD), since the light sensor is arranged below the display area, when the anode area of the light-emitting element is reduced, more space can be freed up for light transmission, thereby increasing the light transmittance of the fingerprint recognition area under the screen and improving the fingerprint recognition effect.
[0042] The display panel provided by the embodiment of the present application is arranged in an array of multiple pixel repeating units in the display panel by setting two first sub-pixels, two second sub-pixels and four third sub-pixels to form a pixel repeating unit, and there is a first sub-pixel located between the four third sub-pixels, there is a second sub-pixel located between the four third sub-pixels, and there is a third sub-pixel located between the two first sub-pixels and the two second sub-pixels. Compared with the existing RGBG or YYG arrangement, the first sub-pixel, the second sub-pixel and the third sub-pixel can be distributed more evenly in the display panel, thereby improving the display effect of the display panel; in addition, by setting the centers of the four third sub-pixels surrounding the first sub-pixel to form a first irregular trapezoid with two groups of opposite sides of unequal lengths, the design space of the display area can be fully utilized, and the pixel arrangement can be made more compact. Moreover, based on the design of the irregular trapezoid, the pixel resolution can be ensured by reducing the light-emitting area of the third sub-pixel. Accordingly, the mask opening area can be reduced to improve the strength of the mask, and the anode area of the light-emitting element can be reduced to improve the light transmittance of the fingerprint recognition area under the screen, thereby improving the fingerprint recognition effect.
[0043] Continue to see Figure 1 and Figure 2, the wireframe around the first sub-pixel 11 represents the virtual edge 111 of the first sub-pixel 11, the wireframe around the second sub-pixel 12 represents the virtual edge 121 of the second sub-pixel 12, and the wireframe around the third sub-pixel 13 represents the virtual edge 131 of the third sub-pixel 13, wherein the virtual edge refers to the outer boundary of the sub-pixel when the Mask is blocked, and does not really exist. Optionally, different mask plates can be used to prepare the pixel openings of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 in different processes to avoid mutual influence and reduce the difficulty of preparation. In addition, optionally, the virtual edge 131 of the third sub-pixel 13 is connected to the virtual edges 111 of the two adjacent first sub-pixels 11, and the virtual edge 131 of the third sub-pixel 13 is connected to the virtual edges 121 of the two adjacent second sub-pixels 12. In this way, the arrangement of the first sub-pixel 11 , the second sub-pixel 12 and the third sub-pixel 13 can be made more compact without obvious hollow areas, which can effectively avoid obvious spacing gaps, avoid space waste, and avoid possible dark mura.
[0044] Continue to see Figure 1 Optionally, the centers of the four third sub-pixels 13 surrounding the second sub-pixel 12 form a second irregular trapezoid 22, wherein the lengths of the two sets of opposite sides of the second irregular trapezoid 22 are not equal. By setting the centers of the four third sub-pixels 13 surrounding the second sub-pixel 12 to form a second irregular trapezoid 22 with two sets of unequal opposite sides, the design space of the display area can be fully utilized to make the pixel arrangement more compact, and based on the design of the irregular trapezoid, the pixel resolution can be guaranteed by reducing the light-emitting area of the third sub-pixel. Accordingly, the mask opening area can be reduced to improve the strength of the mask, and the anode area of the light-emitting element can also be reduced to improve the light transmittance of the fingerprint recognition area under the screen, thereby improving the fingerprint recognition effect. The specific principle is described above and will not be repeated here.
[0045] Continue to see Figure 1 , Optionally, the light emitting areas of the third sub-pixels 13 are equal.
[0046] like Figure 1 As shown, four third sub-pixels 13 surround one first sub-pixel 11, or four third sub-pixels 13 surround one second sub-pixel 12. In this way, when the setting area of the third sub-pixel 13 is determined, the setting area of the first sub-pixel 11 and the second sub-pixel 12 can be determined. In the embodiment of the present application, the light-emitting areas of the third sub-pixels 13 are set equal, which can reduce the difficulty of design and manufacturing process.
[0047] In this embodiment, when the centers of the four third sub-pixels 13 surrounding the first sub-pixel 11 form a second irregular trapezoid 22, and the centers of the four third sub-pixels 13 surrounding the second sub-pixel 12 form a second irregular trapezoid 22, and the light-emitting areas of the third sub-pixels 13 are equal, the light-emitting areas of the two first sub-pixels 11 in the pixel repeating unit can be unequal, and / or the light-emitting areas of the two second sub-pixels 12 can be unequal. Figure 1 and Figure 2 As shown, the light-emitting areas of the two first sub-pixels 11 and the two second sub-pixels 12 in the pixel repeating unit are not equal. In this way, the display panel can have first sub-pixels 11 and / or second sub-pixels 12 with two light-emitting areas, thereby meeting different design requirements.
[0048] For example, in an actual application scenario, as the PPI increases, the opening area (light-emitting area) of the sub-pixel is smaller, so the driving current needs to be increased to meet the display brightness requirements. However, OLED working under a large driving current is prone to device aging, shortening the life of the display device. The embodiment of the present application forms sub-pixels with different opening areas (i.e., the first sub-pixel 11 and / or the second sub-pixel 12) through pixel arrangement, so that the sub-pixel with a smaller opening area can be driven based on the driving current corresponding to the sub-pixel with a larger opening area. Since the driving current corresponding to the sub-pixel with a larger opening area is smaller at the same brightness, the phenomenon of device aging caused by a large driving current can be avoided, thereby extending the life of the display device.
[0049] For example, in another actual application scenario, in order to achieve a full screen, under-screen camera technology came into being. In order to achieve under-screen camera, the display area corresponding to the location of the camera needs to be light-transmissive. In the embodiment of the present application, sub-pixels with different opening areas are formed by pixel arrangement (i.e., the first sub-pixel 11 and / or the second sub-pixel 12). The sub-pixels with larger opening areas can be removed in the under-screen camera placement area to achieve light transmission and improve light transmittance. At the same time, the sub-pixels with smaller opening areas can be retained to ensure that the under-screen camera placement area can achieve display, thereby achieving full-screen display.
[0050] Continue to see Figure 1 Optionally, the distances between the first sub-pixel 11 and its four nearest neighboring first sub-pixels 11 are equal.
[0051] The distance between two first sub-pixels 11 may refer to the center distance between the two. Figure 1 As shown, for the first sub-pixel 11 surrounded by the four third sub-pixels 13 in the 2nd and 3rd columns of the 4th row and the 2nd and 3rd columns of the 5th row, the distances between the first sub-pixel 11 and its four nearest first sub-pixels 11 are equal, so that the arrangement of the first sub-pixels 11 can be more uniform.
[0052] Continue to see Figure 1 Optionally, the distances between the second sub-pixel 12 and its four nearest second sub-pixels 12 are equal.
[0053] The distance between two second sub-pixels 12 may refer to the center distance between the two. Figure 1 As shown, for the second sub-pixel 12 surrounded by the four third sub-pixels 13 in the 3rd and 4th columns of the 4th row and the 3rd and 4th columns of the 5th row, the distances between the second sub-pixel 12 and its four nearest first sub-pixels 11 are equal, so that the arrangement of the second sub-pixels 12 can be more uniform.
[0054] Continue to see Figure 1 Optionally, the centers of the four second sub-pixels 12 that are closest to the same first sub-pixel 11 form a first rectangle 31, the first diagonal line of the first rectangle 31 is parallel to the first direction, and the second diagonal line of the first rectangle 31 is parallel to the second direction; the first direction intersects the second direction ( Figure 1 Take the example of the two being orthogonal to illustrate).
[0055] like Figure 1 As shown, for the first sub-pixel 11 surrounded by the four third sub-pixels 13 in the 2nd row, 4th column and 5th column and the 3rd row, 4th column and 5th column, the centers of the four second sub-pixels 12 closest to it form a first rectangle 31, and the two diagonal lines of the first rectangle 31 are parallel to the first direction and the second direction respectively, so that the arrangement of the second sub-pixels 12 can be more uniform. Further, the shape of the second sub-pixel 12 can be a rectangle, such as Figure 1 As shown, the two sets of opposite sides of the second sub-pixel 12 can be respectively parallel to the two sets of opposite sides of the first rectangle 31, so as to make full use of the space surrounded by the four third sub-pixels 13 and make the pixel arrangement more compact. In addition, when the distances between the second sub-pixel 12 and the four second sub-pixels 12 closest to it are equal, the first rectangle 31 is a square.
[0056] Optionally, the centers of the four first sub-pixels 11 that are closest to the same second sub-pixel 12 form a second rectangle 32, the first diagonal of the second rectangle 32 is parallel to the first direction, and the second diagonal of the second rectangle 32 is parallel to the second direction; the first direction and the second direction intersect.
[0057] like Figure 1As shown, for the second sub-pixel 12 surrounded by the four third sub-pixels 13 in the 2nd row, 3rd column and 4th column and the 3rd row, 3rd column and 4th column, the centers of the four first sub-pixels 11 closest to it form a second rectangle 32, and the two diagonal lines of the second rectangle 32 are parallel to the first direction and the second direction respectively, so that the arrangement of the first sub-pixels 11 can be more uniform. Further, the shape of the first sub-pixel 11 can be a rectangle, such as Figure 1 As shown, the two sets of opposite sides of the first sub-pixel 11 can be respectively parallel to the two sets of opposite sides of the second rectangle 32, so as to make full use of the space surrounded by the four third sub-pixels 13 and make the pixel arrangement more compact. In addition, when the distance between the first sub-pixel 11 and the four first sub-pixels 11 closest to it is equal, the second rectangle 32 is a square.
[0058] Continue to see Figure 1 Optionally, the shapes of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are all rectangular, and the aspect ratio L / W of the rectangles satisfies 1≤L / W≤1.5.
[0059] Taking into account the mesh and mask process, the larger the aspect ratio, the easier it is for the mesh to deform and the greater the degree of deformation. Moreover, during anisotropic etching, the etching accuracy in each direction is difficult to control. Therefore, the aspect ratio of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 can be selected to be between 1 and 1.5 to ensure production yield and reduce process difficulty.
[0060] It should be noted that Figure 1 The pixel arrangement shown is only an example and is not limiting. As described above, when the setting area of the third sub-pixel 13 is determined, the setting areas of the first sub-pixel 11 and the second sub-pixel 12 are determined accordingly. Below, based on different arrangements of the third sub-pixel 13, the pixel arrangement in the display panel is further described in detail. The arrangement characteristics of each sub-pixel described in the above embodiment are applicable to any of the following pixel arrangements and will not be repeated later.
[0061] Figure 3-Figure 9 is a schematic diagram of the structure of another display panel provided in an embodiment of the present application, see Figure 1 and Figure 3-Figure 9 Optionally, among the third sub-pixels 13 arranged along the first direction, the center line of the third sub-pixels 13 in the odd rows is the first wavy line 41, and the center line of the third sub-pixels 13 in the even rows is the first straight line 51; or, the center line of the third sub-pixels 13 in the odd rows is the first straight line 51, and the center line of the third sub-pixels 13 in the even rows is the first wavy line 41; wherein the first direction is the row direction or the column direction.
[0062] Figure 1-Figure 9The first direction is taken as a column direction as an example for illustration. In other embodiments, the first direction may also be a row direction. No further examples are given here.
[0063] For example, Figure 1 , Figure 3 , Figure 4 and Figure 8 In the display panel shown, among the third sub-pixels 13 arranged along the first direction, the center line of the third sub-pixels 13 in the odd-numbered rows is the first wavy line 41, and the center line of the third sub-pixels 13 in the even-numbered rows is the first straight line 51; Figure 5 , Figure 6 , Figure 7 and Fig. 9 In the display panel shown, among the third sub-pixels 13 arranged along the first direction, the center line connecting the third sub-pixels 13 in odd-numbered rows is a first straight line 51 , and the center line connecting the third sub-pixels 13 in even-numbered rows is a first wavy line 41 .
[0064] In the embodiment of the present application, by arranging the third sub-pixels 13 arranged along the first direction, the center connecting lines of each row of the third sub-pixels 13 are arranged alternately as straight lines and wavy lines, so that the two opposite sides extending along the first direction in the first irregular trapezoid 21 are not parallel and have unequal lengths, and thus the lengths of another group of opposite sides can be made unequal, thereby ensuring that the lengths of the two groups of opposite sides of the first irregular trapezoid 21 are unequal. Similarly, the lengths of the two groups of opposite sides of the second irregular trapezoid 22 can be ensured to be unequal.
[0065] See also Figure 2 and Figure 3 Optionally, a distance between a line connecting the highest points in the first wave line 41 and a line connecting the lowest points in the first wave line 41 is D1, wherein 0<D1≤L1 / 8, L1 is the length of the pixel setting area 10 along the second direction; the second direction intersects with the first direction, and the pixel setting area 10 covers the entire area of a first sub-pixel 11 and a partial area of four third sub-pixels 13 surrounding the first sub-pixel 11, or covers the entire area of a second sub-pixel 12 and a partial area of four third sub-pixels 13 surrounding the second sub-pixel 12.
[0066] The meaning of the pixel setting area 10 is explained above and will not be repeated here. In the embodiment of the present application, by setting the distance between the highest point line in the first wave line 41 and the lowest point line in the first wave line 41 to be less than or equal to 1 / 8 of the length of the pixel set along the second direction, not only can the centers of the four third sub-pixels 13 surrounding the first sub-pixel 11 or the second sub-pixel 12 form two groups of irregular quadrilaterals with unequal opposite side lengths through a "wave" arrangement, but also the third sub-pixels arranged in a wave-like manner along the first direction can be prevented from being too undulating and affecting the display effect.
[0067] It should be noted that the drawings all illustrate by taking the example that the first direction and the second direction are orthogonal, the first direction is the column direction, and the second direction is the row direction.
[0068] Furthermore, the third sub-pixels 13 arranged along the second direction may have a variety of different arrangements.
[0069] As one possible implementation, see Figure 3-Figure 6 Optionally, among the third sub-pixels 13 arranged along the second direction, the center line of the third sub-pixels 13 in the odd rows is the second wavy line 42, and the center line of the third sub-pixels 13 in the even rows is the second straight line 52; or, the center line of the third sub-pixels 13 in the odd rows is the second straight line 52, and the center line of the third sub-pixels 13 in the even rows is the second wavy line 42; the second direction intersects with the first direction.
[0070] For example, Figure 3 and Figure 5 For example, among the third sub-pixels 13 arranged along the second direction, the center line of the third sub-pixels 13 in odd rows is the second wavy line 42, and the center line of the third sub-pixels 13 in even rows is the second straight line 52; Figure 4 and Figure 6 For example, among the third sub-pixels 13 arranged along the second direction, the center line of the third sub-pixels 13 in odd rows is the second straight line 52 , and the center line of the third sub-pixels 13 in even rows is the second wavy line 42 .
[0071] Specifically, Figure 3 In the figure, the third sub-pixels 13 in odd-numbered rows and odd-numbered columns are arranged in a wave-like manner, and the third sub-pixels 13 in even-numbered rows and even-numbered columns are arranged in a straight line; Figure 4 In the figure, the third sub-pixels 13 in the even-numbered rows and odd-numbered columns are arranged in a wave-like manner, and the third sub-pixels 13 in the odd-numbered rows and even-numbered columns are arranged in a straight line; Figure 5 In the figure, the third sub-pixels 13 in odd-numbered rows and even-numbered columns are arranged in a wave-like manner, and the third sub-pixels 13 in even-numbered rows and odd-numbered columns are arranged in a straight line; Figure 6 In the embodiment, the third sub-pixels 13 in even-numbered rows and even-numbered columns are arranged in a wave-like manner, and the third sub-pixels 13 in odd-numbered rows and odd-numbered columns are arranged in a straight line.
[0072] from Figure 3-Figure 6It can be seen that the quadrilateral formed by the centers of the four third sub-pixels 13 surrounding the first sub-pixel 11 is an irregular quadrilateral with two sets of unequal opposite sides, and the quadrilateral formed by the centers of the four third sub-pixels 13 surrounding the second sub-pixel 12 is an irregular quadrilateral with two sets of unequal opposite sides. In this case, the light-emitting areas of the two first sub-pixels 11 adjacent to the same third sub-pixel 13 can be different, or the light-emitting areas of the two second sub-pixels 12 adjacent to the same third sub-pixel 13 can be different. For example, Figure 3 and Figure 5 In the embodiment, the light-emitting areas of the two second sub-pixels 12 adjacent to the same third sub-pixel 13 are different, and the light-emitting areas of the two first sub-pixels 11 adjacent to the same third sub-pixel 13 are the same; Figure 4 and Figure 6 In the embodiment, the light-emitting areas of two first sub-pixels 11 adjacent to the same third sub-pixel 13 are different, and the light-emitting areas of two second sub-pixels 12 adjacent to the same third sub-pixel 13 are the same. In this way, the display panel can have two types of first sub-pixels 11 with light-emitting areas or two types of second sub-pixels 12 with light-emitting areas, thereby meeting different design requirements. For details, please refer to the above explanation and will not be repeated here.
[0073] Combination Figure 2 and Figure 3 Further optionally, a distance D2 between a line connecting the highest points in the second wave line 42 and a line connecting the lowest points in the second wave line 42 satisfies 0<D2≤L2 / 8, where L2 is the length of the pixel setting area 10 along the first direction.
[0074] As another possible implementation, see Figure 1 and Figure 7 Optionally, a center line of the third sub-pixels 13 arranged along the second direction is a third wavy line 43, and the second direction intersects the first direction.
[0075] like Figure 1 and Figure 7 As shown, the center lines of the third sub-pixels 13 arranged along the second direction are all third wavy lines 43, and the only difference is that the arrangement of the third sub-pixels 13 arranged in the first direction is different. Specifically, Figure 1 In the embodiment, the third sub-pixels 13 of all rows are arranged in a wave-like manner, the third sub-pixels 13 of odd-numbered columns are arranged in a wave-like manner, and the third sub-pixels 13 of even-numbered columns are arranged in a straight line; Figure 7 In the embodiment of the present application, the third sub-pixels 13 arranged along the second direction are arranged in a wave-like manner, the third sub-pixels 13 in the even-numbered columns are arranged in a wave-like manner, and the third sub-pixels 13 in the odd-numbered columns are arranged in a straight line. In this embodiment of the present application, the third sub-pixels 13 arranged along the second direction are arranged in a wave-like manner, so that the arrangement method is simpler and the manufacturing difficulty can be reduced.
[0076] from Figure 1 and Figure 7 It can be seen that the quadrilateral formed by the centers of the four third sub-pixels 13 surrounding the first sub-pixel 11 is an irregular trapezoid with two sets of unequal opposite sides, and the quadrilateral formed by the centers of the four third sub-pixels 13 surrounding the second sub-pixel 12 is an irregular trapezoid with two sets of unequal opposite sides. At this time, the light-emitting areas of the two first sub-pixels 11 adjacent to the same third sub-pixel 13 are different, and the light-emitting areas of the two second sub-pixels 12 adjacent to the same third sub-pixel 13 are different. In this way, the display panel can have two types of first sub-pixels 11 with light-emitting areas and two types of second sub-pixels 12 with light-emitting areas, thereby meeting different design requirements. Please refer to the above explanation for details and will not be repeated here.
[0077] Optionally, in each third wavy line 43, the distance between the highest point line and the lowest point line is equal; the centers of four adjacent third sub-pixels 13 form an irregular trapezoid; the centers of two first sub-pixels 11 and two second sub-pixels 12 adjacent to the same third sub-pixel 13 form an isosceles trapezoid 6.
[0078] See also Figure 7 When the distances between the highest point line and the lowest point line in each third wavy line 43 are equal, each third wavy line 43 is parallel to each other, so that the centers of four adjacent third sub-pixels 13 surrounding the first sub-pixel 11 or the second sub-pixel 12 can form an irregular trapezoid, and the centers of two first sub-pixels 11 and two second sub-pixels 12 adjacent to the same third sub-pixel 13 can form an isosceles trapezoid 6, making the pixel arrangement more uniform.
[0079] Combination Figure 2 and Figure 7 , Optionally, the distance D3 between the line connecting the highest point in the third wavy line 43 and the line connecting the lowest point in the third wavy line 43 satisfies 0<D3≤L2 / 8. Further, the isosceles trapezoid 6 includes a first side 61 and a second side 62 parallel to the first direction; the length a of the first side 61 and the length b of the second side 62 satisfy 0<|ab|≤L2 / 4; L2 is the length of the pixel setting area 10 along the first direction; the pixel setting area 10 covers the entire area of a first sub-pixel 11 and the partial area of four third sub-pixels 13 surrounding the first sub-pixel 11, or covers the entire area of a second sub-pixel 12 and the partial area of four third sub-pixels 13 surrounding the second sub-pixel 12.
[0080] The meaning of the pixel setting area 10 is explained above and will not be repeated here. The distance D3 between the line connecting the highest point in the third wave line 43 and the line connecting the lowest point in the third wave line 43 satisfies 0<D3≤L2 / 8, which can avoid the third sub-pixel 13 arranged in a wave-like manner along the second direction from having too large an undulation degree and affecting the display effect. Given 0<D3≤L2 / 8, it can be obtained that the length difference between the first side 61 and the second side 62 of the isosceles trapezoid 6 satisfies 0<|ab|≤L2 / 4.
[0081] As another possible implementation method, see Figure 8 and Fig. 9 Optionally, a line connecting the centers of the third sub-pixels 13 arranged along the second direction is a third straight line 53, and the second direction intersects the first direction.
[0082] like Figure 8 and Fig. 9 As shown, the center lines of the third sub-pixels 13 arranged along the second direction are all the third straight line 53, and the only difference is that the arrangement of the third sub-pixels 13 arranged in the first direction is different. Specifically, Figure 8 In the embodiment, the third sub-pixels 13 of all rows are arranged in a straight line, the third sub-pixels 13 of odd columns are arranged in a wave-like manner, and the third sub-pixels 13 of even columns are arranged in a straight line; Fig. 9 In the embodiment of the present application, the third sub-pixels 13 arranged along the second direction are arranged in a straight line, the third sub-pixels 13 of the even-numbered columns are arranged in a wave-like manner, and the third sub-pixels 13 of the odd-numbered columns are arranged in a straight line. The arrangement method is simpler and the manufacturing difficulty can be reduced by setting the third sub-pixels 13 arranged along the second direction in a straight line.
[0083] from Figure 8 and Fig. 9 It can be seen that the quadrilateral formed by the centers of the four third sub-pixels 13 surrounding the first sub-pixel 11 is an irregular trapezoid with two sets of unequal opposite sides, and the quadrilateral formed by the centers of the four third sub-pixels 13 surrounding the second sub-pixel 12 is an irregular trapezoid with two sets of unequal opposite sides. At this time, the light-emitting areas of the two first sub-pixels 11 adjacent to the same third sub-pixel 13 are different, and the light-emitting areas of the two second sub-pixels 12 adjacent to the same third sub-pixel 13 are different. In this way, the display panel can have two types of first sub-pixels 11 with light-emitting areas and two types of second sub-pixels 12 with light-emitting areas, thereby meeting different design requirements. Please refer to the above explanation for details and will not be repeated here.
[0084] In summary, the above embodiments provide a detailed description of the pixel arrangement in the display panel based on different arrangements of the third sub-pixels 13. In summary, the third sub-pixels 13 can be arranged in a variety of different ways, so that the centers of the four third sub-pixels 13 surrounding the first sub-pixel 11 form an irregular trapezoid with two sets of unequal opposite sides, and the centers of the four third sub-pixels 13 surrounding the second sub-pixel 12 form an irregular trapezoid with two sets of unequal opposite sides, so that the display panel can have first sub-pixels 11 with different light-emitting areas and / or second sub-pixels 12 with different light-emitting areas. , so that the design space can be fully utilized, the aperture ratio can be improved, the life of the display device can be extended, the pixels can be arranged evenly without obvious hollow areas, obvious spacing gaps can be effectively avoided, possible display defects such as dark lines and mura can be avoided, and the display effect can be improved; moreover, based on the design that the third sub-pixel 13 forms an irregular trapezoid, the pixel resolution can be guaranteed by reducing the light-emitting area of the third sub-pixel 13. Accordingly, the opening area of the mask can be reduced to improve the strength of the mask, and the anode area of the light-emitting element can be reduced, thereby improving the light transmittance of the fingerprint recognition area under the screen and improving the fingerprint recognition effect.
[0085] In addition, reference Figure 1 and Figure 2-Figure 9 , taking the first sub-pixel 11 as a blue sub-pixel, the second sub-pixel 12 as a red sub-pixel, and the third sub-pixel 13 as a green sub-pixel as an example, since the human eye is very sensitive to green, by adopting the above-mentioned wavy line arrangement of the third sub-pixel 13, and arranging the third sub-pixels 13 at the four edges in the form of wavy lines, only part of the third sub-pixels 13 can be close to the edge of the display area, and the rest of the third sub-pixels 13 can be indented into the display area, thereby reducing the area proportion of the third sub-pixel 13 in the edge area and weakening the green color edge effect. Exemplary, refer to Figure 1 , for the upper edge, the third sub-pixels 13 are arranged in the form of wavy lines, the third sub-pixels 13 located in odd columns at the upper edge are closer to the edge, and the third sub-pixels 13 located in even columns at the upper edge are indented toward the inside of the display area, so the area proportion of the third sub-pixels 13 in the edge area is reduced, and the green color edge effect is weakened. It can be understood that by adjusting the number of columns and rows of sub-pixels, it can be ensured that the third sub-pixels 13 at the four edges are arranged in the form of wavy lines. Among them, the width of the edge area can be the width of one sub-pixel from the edge.
[0086] It should be noted that Figure 1 and Figure 2-Figure 9 The structure shown only takes the third sub-pixel 13 being located at the four edges of the display area as an example, and this layout is not limiting.
[0087] For example, Fig.10is a schematic diagram of the structure of another display panel provided in an embodiment of the present application, see Fig.10 Optionally, the display panel also includes a display area AA; the display area AA includes a first edge and a second edge opposite to each other along a first direction; the first edge includes a first pixel row 101, the first pixel row 101 includes a first sub-pixel 11 and at most a portion of a second sub-pixel 12, and does not include a third sub-pixel 13.
[0088] Exemplarily, the first sub-pixel 11 is a blue sub-pixel, the second sub-pixel 12 is a red sub-pixel, and the third sub-pixel 13 is a green sub-pixel. Fig.10 For illustration, an example is given in which the first direction is the column direction, the second direction is the row direction, the first edge is the upper edge, and the second edge is the lower edge.
[0089] If a rectangle is formed by the centers of two first sub-pixels and two second sub-pixels around a third sub-pixel, and a rectangle is formed by the centers of four third sub-pixels around a second sub-pixel and / or around a first sub-pixel (for example, a diamond arrangement), the first sub-pixel (blue sub-pixel) and the second sub-pixel (red sub-pixel) close to the first edge will form a magenta color fringing, and the third sub-pixel (green sub-pixel) close to the second edge will form a green color fringing.
[0090] As described above, the technical solution of the embodiment of the present application can make the light-emitting areas of two first sub-pixels 11 adjacent to the same third sub-pixel 13 different, and / or the light-emitting areas of two second sub-pixels 12 adjacent to the same third sub-pixel 13 different, by designing the four third sub-pixels 13 surrounding a first sub-pixel 11 and / or surrounding a second sub-pixel 12 to form an irregular trapezoid, so that the center points of the first sub-pixels 11 and the second sub-pixels 12 located in the same row in the first direction and / or the second direction are not on a straight line (see Figure 1-Figure 9 ).like Fig.10 As shown, the first sub-pixels 11 and the second sub-pixels 12 arranged along the second direction are arranged in a wavy line, so that the first pixel row 101 can include the first sub-pixels 11 and at most a part of the second sub-pixels 12, or even only the first sub-pixels 11, so that there are only blue sub-pixels on the first edge, thereby weakening the magenta color edge effect. Moreover, the human eye is not sensitive to blue, so the color edge effect is weak.
[0091] Continue to see Fig.10 Optionally, the second edge includes a second pixel row 102 , the second pixel row 102 includes a third sub-pixel 13 and at least a portion of the second sub-pixel 12 , and does not include the first sub-pixel 11 .
[0092] Referring to the above description, the first sub-pixel 11 and the second sub-pixel 12 arranged along the second direction can be arranged in a wavy line. Therefore, at the second edge opposite to the first edge, the second pixel row 102 may include the third sub-pixel 13 and at least part of the second sub-pixel 12, or even the third sub-pixel 13 and all the second sub-pixels 12. At this time, since the red sub-pixel is close to the second edge, the green color edge effect of the second edge in the diamond arrangement can be weakened.
[0093] Continue to see Fig.10 Optionally, the display area AA includes a third edge and a fourth edge opposite to each other along the second direction; the third edge includes a third pixel row 103, the third pixel row 103 includes a first sub-pixel 11, a second sub-pixel 12 and a portion of a third sub-pixel 13; the portion of the third sub-pixels 13 include third sub-pixels 13 located at odd positions arranged along the first direction, or third sub-pixels 13 located at even positions arranged along the first direction; wherein the second direction intersects with the first direction.
[0094] As shown in Figure 10, the third edge is the left edge and the fourth edge is the right edge. Referring to the above description, it can be understood that the left edge of the diamond arrangement is prone to magenta color edge effect, and the right edge is prone to green edge effect. Fig.10 As shown, in the embodiment of the present application, along the second direction, since the rows of third sub-pixels 13 arranged along the first direction are arranged in straight lines and wavy lines, some of the third sub-pixels 13 can be close to the third edge, for example, Fig.10 In the first direction, at least part of the third sub-pixels 13 located at odd positions are close to the third edge, so that the third pixel row 103 includes the first sub-pixel 11, the second sub-pixel 12 and part of the third sub-pixel 13. Since the third sub-pixel 13 is close to the third edge, the magenta color fringing effect of the third edge in the diamond arrangement can be weakened. In other embodiments, at least part of the third sub-pixels 13 located at even positions may be close to the third edge, which will not be repeated here.
[0095] Continue to see Fig.10 Optionally, the fourth edge includes a fourth pixel row 104, the fourth pixel row 104 includes third sub-pixels 13 located at odd positions arranged along the first direction, or the fourth pixel row 104 includes third sub-pixels 13 located at even positions arranged along the first direction; the fourth pixel row 104 does not include the first sub-pixel 11 and the second sub-pixel 12.
[0096] Similarly, in the embodiment of the present application, along the second direction, since the rows of third sub-pixels 13 arranged along the first direction are arranged in straight lines and wavy lines at intervals, some of the third sub-pixels 13 can be kept away from the fourth edge. For example, at least some of the third sub-pixels 13 arranged along the first direction and located at odd positions can be kept away from the fourth edge, or at least some of the third sub-pixels 13 arranged along the first direction and located at even positions can be kept away from the fourth edge. In this way, the number of green sub-pixels at the fourth edge can be reduced, thereby weakening the green color fringing effect at the fourth edge in the diamond arrangement.
[0097] It should be understood that the above Fig.10 The first subpixels / second subpixels / third subpixels included in the first pixel row, the second pixel row, the third pixel row, and the fourth pixel row only refer to a row of first subpixels / second subpixels / third subpixels close to the most corresponding edge.
[0098] The following is based on Figure 7 As shown, the centers of two first sub-pixels 1111 and two second sub-pixels 1212 adjacent to the same third sub-pixel 13 form an isosceles trapezoid 6, which further illustrates the display panel.
[0099] Fig.11 is a partial structural diagram of a display panel provided in an embodiment of the present application, Fig.12 is with Fig.11 For a cross-sectional structural diagram of the corresponding display panel, see Fig.11 and Fig.12 Optionally, the display panel includes a substrate 71 and a support column 76, and in a direction perpendicular to the plane where the substrate 71 is located, the support column 76 overlaps with the longer one of the first edge 61 and the second edge 62.
[0100] For details, see Fig.12 The display panel may further include a plurality of pixel circuit layers 72 located on one side of the substrate 71 and a display layer 73 located on the side of the pixel circuit layer 72 away from the substrate 71, the display layer 73 includes a pixel defining layer 732 and a plurality of light emitting elements 731, and the display panel may further include a support column 76 located on the side of the pixel defining layer 732 away from the substrate 71; the pixel defining layer 732 includes a plurality of pixel openings, and the plurality of pixel openings may be arranged corresponding to the plurality of light emitting elements 731; in combination with Fig.11 In a direction perpendicular to the plane where the substrate 71 is located, the support column 76 overlaps with the longer one of the first side 61 and the second side 62 .
[0101] The pixel circuit layer 72 may include a plurality of pixel circuits for driving the light-emitting element to emit light. Fig.12Only the structure of some transistors in the pixel circuit layer 72 is shown, and the specific structure of the pixel circuit is not described in detail here. Those skilled in the art can design the required pixel circuit according to the needs. The light-emitting colors of the light-emitting elements in the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are different. For example, the first sub-pixel 11 includes a first light-emitting element, and the light-emitting color of the first light-emitting element is blue. The second sub-pixel 12 includes a second light-emitting element, and the light-emitting color of the second light-emitting element is red. The third sub-pixel 13 includes a third light-emitting element, and the light-emitting color of the third light-emitting element is green. Fig.12 As shown, the light emitting element 731 may include an anode 7311 , a light emitting layer 7312 and a cathode 7313 , and a pixel opening in the pixel defining layer 732 is arranged corresponding to the light emitting element 731 .
[0102] For the specific preparation process, refer to Fig.12 After forming a pixel opening on the pixel defining layer 732 to expose the anode 7311, a mask is used to evaporate the corresponding light-emitting material in the pixel opening to form a light-emitting layer 7312. Optionally, the light-emitting layers 7312 of light-emitting elements of different light-emitting colors can be evaporated using different masks. In order to avoid direct contact between the mask and the pixel defining layer 732, a support column 76 needs to be provided above the pixel defining layer 732 to support the mask.
[0103] like Fig.11 As shown, since the first side 61 and the second side 62 of the isosceles trapezoid formed by the two first sub-pixels 11 and the two second sub-pixels 12 adjacent to the same third sub-pixel 13 have a length difference, the embodiment of the present application sets the support column 76 to overlap with the longer one of the first side 61 and the second side 62, that is, the support column 76 is set above the pixel defining layer 732 between the first sub-pixel opening and the second sub-pixel opening with a larger distance, so that the support column 76 has a larger setting space; in addition, for support columns 76 of the same size, this solution can make the support column 76 have a larger distance from the first sub-pixel opening and the second sub-pixel opening, thereby avoiding the support column 76 from blocking the light emitted by the light-emitting element 731 and reducing color deviation. Exemplary, Fig.11 The length of the second side 62 of the midsole trapezoid is greater than the length of the first side 61 , so the support column 76 is arranged to overlap the second side 62 .
[0104] For example, Fig.13 is a schematic diagram of a partial structure of an existing display panel, taking the diamond arrangement as an example. Fig.13 As shown, two first sub-pixels 11 and two second sub-pixels 12 adjacent to the same third sub-pixel 13 form a rectangle. To facilitate the display of contrast effects, Fig.13 The left side 60 of the middle rectangle is Fig.11 The lengths of the first sides 61 of the midsole trapezoids are equal, Fig.13 The first sub-pixel 11 and the second sub-pixel 12 are Fig.11 The first sub-pixel 11 and the second sub-pixel 12 have the same small and medium size, and Fig.11 and Fig.13 The lengths of the middle support columns 76 along the first direction are equal. Fig.11 and Fig.13 It can be seen that Fig.11 The distance b between the middle support column 76 and the first pixel opening and the second pixel opening is greater than Fig.13 The distance c between the middle support column 76 and the first pixel opening and the second pixel opening indicates that the embodiment of the present application can increase the setting space of the support column 76 by setting two first sub-pixels 11 and two second sub-pixels 12 adjacent to the same third sub-pixel 13 to form an isosceles trapezoid, and setting the support column 76 at the position of the long side (such as the second side 62) of the isosceles trapezoid. In addition, for support columns 76 of the same size, the distance between the support column 76 and the first pixel opening and the second pixel opening can be increased, thereby avoiding the support column 76 from blocking the light emitted by the light-emitting element 731 and reducing color deviation.
[0105] Fig.14 is a partial structural diagram of another display panel provided in an embodiment of the present application, Fig.15 is with Fig.14 For a cross-sectional structural diagram of the corresponding display panel, see Fig.14 and Fig.15 Optionally, the display panel may further include a substrate 71, a light shielding layer 74, and a light sensor 75, wherein the light shielding layer 74 includes a plurality of light-transmitting pinholes 740; in a direction perpendicular to the plane where the substrate 71 is located, the light sensor 75 and the light-transmitting pinholes 740 overlap with each other. Optionally, in a direction perpendicular to the plane where the substrate 71 is located, the light-transmitting pinholes 740 overlap with the longer one of the first side 61 and the second side 62.
[0106] The light sensor 75 can be used to realize fingerprint recognition, for example. Specifically, the light shielding layer 74 is provided with a plurality of light-transmitting pinholes 740, and some light-emitting elements 731 in the display layer 73 can be reused as fingerprint recognition light sources. After the light generated by the light-emitting element 731 reaches the contact surface between the fingerprint and the display screen, due to the different degrees of reflection of the light by the fingerprint valley and the fingerprint ridge, the reflected light passes through the light-transmitting pinholes 740 and enters the light sensor 75. Through the principle of pinhole imaging, the fingerprint image is imaged to the light sensor 75 to realize fingerprint recognition.
[0107] like Fig.14As shown, since the first side 61 and the second side 62 of the isosceles trapezoid formed by the two first sub-pixels 11 and the two second sub-pixels 12 adjacent to the same third sub-pixel 13 have a length difference, the embodiment of the present application sets the light-transmitting hole 740 to overlap with the longer one of the first side 61 and the second side 62, so that there is more space for setting the light-transmitting hole 740, and then the aperture of the light-transmitting hole 740 along the extension direction of the first side 61 / the second side 62 (i.e., the first direction) can be increased. In this way, the light-transmitting area of the light-transmitting hole 740 can be increased, the fingerprint recognition signal amount can be increased, the fingerprint recognition time can be shortened, and the adverse effects caused by the diffraction of the light-transmitting hole 740 can be reduced. Exemplary, Fig.14 The length of the second side 62 of the midsole trapezoid is greater than the length of the first side 61 , so the light-transmitting hole 740 is arranged to overlap with the second side 62 .
[0108] For example, Fig.16 is a schematic diagram of a partial structure of another existing display panel, taking the diamond arrangement as an example. Fig.16 As shown, two first sub-pixels 11 and two second sub-pixels 12 adjacent to the same third sub-pixel 13 form a rectangle. To facilitate the display of contrast effects, Fig.16 The left side 60 of the middle rectangle is Fig.14 The lengths of the first sides 61 of the midsole trapezoids are equal, Fig.16 The first sub-pixel 11 and the second sub-pixel 12 are Fig.14 The first sub-pixel 11 and the second sub-pixel 12 of small and medium sizes are consistent and along the first direction, Fig.14 and Fig.16 The distances between the middle light-transmitting hole (740 / 740') and the first sub-pixel 11 and the second sub-pixel 12 are equal, both being e. Fig.14 and Fig.16 It can be seen that along the first direction, Fig.14 The aperture of the light-transmitting aperture 740 is larger than Fig.16 The aperture of the middle light-transmitting hole 740' indicates that the embodiment of the present application forms an isosceles trapezoid by arranging two first sub-pixels 11 and two second sub-pixels 12 adjacent to the same third sub-pixel 13, and arranging the light-transmitting hole 740 at the position of the long side (such as the second side 62) of the isosceles trapezoid, thereby increasing the aperture of the light-transmitting hole 740 along the first direction, thereby increasing the light-transmitting area of the light-transmitting hole 740, increasing the fingerprint recognition signal amount, shortening the fingerprint recognition time, and reducing the adverse effects of the diffraction of the light-transmitting hole 740.
[0109] It should be noted that the embodiment of the present application does not limit the number of light shielding layers 74. Fig.15Taking the light shielding layer 74 including the first light shielding layer 741 and the second light shielding layer 742 as an example, in other embodiments, the display panel may include only one light shielding layer 74. Other structures in the display panel can refer to the description of the above embodiment and will not be repeated here.
[0110] refer to Figure 7 The first side 61 and the second side 62 of the isosceles trapezoid are parallel to the first direction. At this time, considering the process yield problem, optionally, the first direction is the column direction and the second direction is the row direction.
[0111] Specifically, in the evaporation process of the light-emitting layer, for example, an angle plate is provided in the first direction, while an angle plate is not provided in the second direction. When an angle plate is provided in the first direction, the light-emitting layer 7312 of each sub-pixel arranged in the first direction has a high evaporation precision during evaporation, which can prevent the light-emitting material of the light-emitting layer of the first sub-pixel 11 from falling into the pixel opening corresponding to the adjacent second sub-pixel 12, or the light-emitting material of the light-emitting layer of the second sub-pixel 12 from falling into the pixel opening corresponding to the adjacent first sub-pixel 11; when an angle plate is not provided in the second direction, the evaporation precision is relatively low. At this time, if the distance between the adjacent first sub-pixel 11 and the second sub-pixel 12 in the second direction is short, the light-emitting material of the light-emitting layer of the first sub-pixel 11 may fall into the pixel opening corresponding to the adjacent second sub-pixel 12, and the light-emitting material of the light-emitting layer of the second sub-pixel 12 may fall into the pixel opening corresponding to the adjacent first sub-pixel 11, resulting in color deviation.
[0112] Therefore, in this embodiment, by increasing the distance between the first sub-pixel 11 and the second sub-pixel 12 in the direction where the angle plate is not set (the second direction), that is, in the second direction, by setting the centers of the first sub-pixel 11 and the second sub-pixel 12 to be located at the two end points of the hypotenuse of the isosceles trapezoid 6 respectively, compared with the existing scheme in which two first sub-pixels 11 and two second sub-pixels 12 adjacent to the same third sub-pixel 13 form a rectangle (such as a diamond arrangement), the distance between the first sub-pixel 11 and the second sub-pixel 12 in the second direction can be increased. In this way, even if the angle plate is not set in the second direction, the evaporation accuracy can be improved to prevent the light-emitting material of the light-emitting layer of the first sub-pixel 11 from falling into the pixel opening corresponding to the adjacent second sub-pixel 12, or the light-emitting material of the light-emitting layer of the second sub-pixel 12 from falling into the pixel opening corresponding to the adjacent first sub-pixel 11, thereby reducing the risk of color deviation, increasing the process margin, and improving the yield.
